"They have hired four actors with bodies very similar to Paul’s physique and they will be used for movement and as a base," an unnamed production source told the paper. "Paul’s face and voice will be used on top using CGI."

Universal hasn't yet responded to THR's request for comment on the use of CGI for Walker's character.

The Hollywood Reporterearlierreported that Universal will use existing footage and screenwriter Chris Morgan worked on revisions that included retiring Walker's character instead of killing him off in the film.

Fast 7 director James Wan along with major cast members -- including Vin Diesel and Michelle Rodriguez -- will travel to the United Arab Emirates to shoot in Abu Dhabi in early April. Filming had been on hold after Walker died in a car crash on Nov. 30.
